Modified Epoxy Non-ferrous Metal Primer

Both epoxy zinc-rich primer and epoxy non-ferrous metal primer are industrial paints. They are both anticorrosive and antirust primer products that can be widely used in a variety of coating environments. The difference between them:

• Product ingredients:

Epoxy zinc-rich primer: a two-component paint, a special coating product composed of epoxy resin, zinc powder, main raw materials, thickeners, fillers, additives, solvents, etc.

Epoxy non-ferrous metal primer: It is a product made up of epoxy resin pigments ground into a color paste as component one and phenolic resin as component two.

• Product appearance:

Epoxy zinc-rich primer: Because zinc powder is used in epoxy zinc-rich primer as an anti-rust pigment, it is dark gray, so epoxy zinc-rich primer is usually only gray.

Epoxy non-ferrous metal primer: Due to the use of lead chrome yellow pigment, the product appearance of epoxy non-ferrous metal primer is yellow.

• Product use:

Epoxy zinc-rich primer: It is mainly suitable for storage tanks, containers, steel structures, steel pipes, offshore platforms, ships, seaport facilities, and base coatings for harsh anti-corrosion environments.

Epoxy non-ferrous metal primer: It can also be used as a primer for anticorrosive coatings for steel structures such as bridges, storage tanks, pipelines, and equipment. The advantage is that it is especially suitable for galvanized sheet, aluminum alloy and other non-ferrous metals. Adhesion is its advantage!

• Respective defects:

Epoxy zinc-rich primer: it is not suitable for use on smooth metal substrates.

Epoxy non-ferrous metal primer: It has a high VOC emission and serious environmental pollution! Heavy metals such as lead in the primer exceed the standard and pose a great threat to human health.

When coating galvanized or other non-ferrous metal surfaces, using ordinary paints such as polyurethane, acrylic, or zinc-rich primers often results in poor adhesion and premature peeling. These coatings fail to form a stable bond with the metal, leading to inadequate corrosion protection and decorative performance.

As a trusted epoxy paint manufacturer, FUXI Coatings provides the Modified Epoxy Non-Ferrous Metal Primer, specially developed for galvanized steel and other non-ferrous substrates. This advanced primer offers excellent adhesion, superior anti-corrosion properties, and strong compatibility with topcoats, ensuring long-lasting surface protection and smooth finishing.
